Jackshaft garage door openers

[GSSFC]

I need to buy two over head door openers. I have the torsion style spring system. The door size is 9' wide x 7' high. There is absolutely NO room to install a traditional style opener. The tracks are pretty much right at the ceiling. I have been told I want a jackshaft style, but have never seen one expect in commercial operations. Anyone recommend a good one? This is my private shop. They will probably be operated 2-3x a day year round.

Check out this link, I have several liftmaster products (door and gate operators) and have had good luck with all.

The LM3800 that is linked above is "the standard" in residential jackshaft openers. Great unit, I love mine.

Byrd,
Does that unit use the electric eyes that mount on the bottom of the door to stop it if someone crosses the path?

I have thought about a jackshaft opener but want one without the sensor eyes. One of the companies I deliver freight to is going to be tearing out part of their loading dock and I may end up getting one of their industrial ones from the dock doors.

All residential openers are required to have photo eyes. Most the time you see people installing them on the wall above the opener... not that i did that...cough, cough.

Hah... yeah I know about that requirement. I could care less about it, too...

Yes they do have both the "electric eyes" that you are referring to and additionally, they also sense if they close on something like a person and will reverse travel. I will be looking into a couple of these when I get to changing my doors to hi-lift. I may also change the ones in my attached garage as well.

Thanks guys, the 3800 is what i was looking at. One question though, how much clearance do you need from the torsion bar and the ceiling. I don't have much. Do they make some adapter so I can use like a chain or pulley to turn the shaft from lower on the wall below it?

Thanks, Tim

Just recently had my new Liftmaster installed. I can't tell you how much better it is than any opener I've ever had. Ditto what all the others said. It also has a wireless keypad on the outside of the door and a positive locking bolt that engages the track every time you shut the door.

Here's a pic:


You can just barely make out the drum between the track and the door. There are a few inches between the torsion bar and the ceiling to allow for the top of the opener and the radius of the drum.

I also have 2 LM3800s and I love them. The door moving makes more noise that the opener does. Mine also came with the remote lights. All you have to do is plug them into a standard 110v outlet, no additional wiring. I disassembled mine and wired it into one bank of lights.

I bought a pair of the liftmaster 3800s about 6 months ago. I finally got around to installing one today. I cant believe how quiet and smooth it is. It more simple to install than the traditional style. Much cleaner looking with nothing cluttering up the cieling too.

Two thumbs up from me!

how close to the ceiling can the shaft be? On mine the drums just about touch the ceiling.

[PurdueSD]

The top of the openener sits below the drums on mine if my memory serves me. I think you need 8" off the side of the rail.

I bought two LM3800s from nova65ss (I can recommend him); not installed yet but I have read the manual, and it seems pretty straightforward. I plan to install myself. In any case my local door supplier quotes $75 to install a customer-supplied opener.

[nova65ss]

It is about 90 bucks or so.

Seriously guys, no need to pay for install. Its rediculous how simple it is. Save the extra 75-150 bucks for tools...
